摘要:Numerical simulation method was applied to study the velocity dispersion properties of laminar flow for the agitation of glycerin in a flat-bottomed cylindrical stirred tank with diameter of 0.21 m, equipped with a Rushton impeller and a pitch 4-bladed turbine. The effects of four different impellers rotating at constant speed of 200 r/min on velocity profiles and power consumption were extensively examined. The results show that the stirred performance of the Rushton impeller was better than one of the pitch 4-bladed turbines, however, accompanied with higher power consumption according to the calculated values of required power. Moreover, there were similar flow characteristics for the pitch 4-bladed turbines with different blade pitch angle. The research provided a theoretical basis for the design and application of the stirred tank with laminar flow.
